To all whom it may concern.-

Be it known that I, JULEs Louis Dunne, engineer, citizen of the French Republic, residing at St. Cloud, Department of Scin -&- Oise, France, (and having post-oilice address 28 larc Moutrctout, in the said city,) have invented certainnew and useful improvements in Oil-ltetaining Devices for Explosion-Motors, of which the following is a speciiication.

It is known that lubricating-oil has a tendency to escape at the joints of the parts that it is intended to lubricate. This tendency is increased and frequently followed by projections of oil outside the heads of conn'ecting-rods or similar parts, owing to the intensity of the centrifugal force. In explosion-motors these defects are aggravated y the fact that the oil is carried into the cylinders, where it is then burned. The result is frequently fouling of the ignitionplugs or, at all events, alosing of lubricatingoil by combustion, which likewise gives rise to1 a visible escape, giving off an unpleasant 0 or.

The invention has for its object to obviate these defects and to collect the oil projected by centrifugal force. I

.In the accompanying drawings, Figure 1 is a partial cross-section through a motor, and Fig. 2 is a partial longitudinal section.

1 is the cranked shaft, and 2 the head of the connecting-rod mounted upon it.

3 3 are two channel-shaped scree s which are fixed upon the crank-case 4. hey are I arranged concentrically to the axis of rotation of the crank and surround its webs, separating them from the cylinder. The oi projected by centrifugal force in the dijrcction of the cylinder 13 stopped by the screens and lows toward their owest point, 1 where it may be collected. It is therefore I ossiblc by means of this arrangement to y lubricate the heads of the connecting-rods and the bearings by means of oil under pressure circulating in the interior of the crank I without danger of a portion of the oil being lost or carried into the cylinders.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- An oil-retaining device for the heads of connecting-rods of explosion-motors, comprising a pair of spaced channelfshaped screens mounted within the crank-case and nesses.
